> When put  "草DX009090" as the value of BillId, which is a field of entity Bill. If I
define a index includes the BillId, and execute the query like "select * from Bill where BillId=’草DX009090‘
in the H2 debug console, there throws an exception by the H2 with a code 5000. 
> another scenario is, I have two entities, "Bill" and "Detail", both have field "BillId".
If either of them have value like "草DX009090" and execute the query like "select bill.*
from bill left join detail on bill.billid=detail.billid", the whole ignite cache node will
halt ( suppose there should be an stack overhead exception, dead loop).
> ======================
> I think the issue should relate to hash computing on the unicode character.
